Abstract
Two new one-dimensional coordination polymers {[CdL2(H2O)2](NO3)2(H2O)6}n (1) and {[CdLI2](H2O)(CH3OH)}n (2) have been synthesized and characterized by IR, elemental analysis, TG technique, XRPD and complete single crystal structure analyses, where L is bis(pyridin-4-ylmethylene)biphenyl-2,2′-dicarbohydrazide. The Cd(II) atom has a distorted octahedral coordination geometry with N4O2 donors from four ligands and two water molecules in 1 and a distorted tetrahedral coordination geometry with NOI2 donors from two ligands and two I− anions in 2, respectively. Polymer 1 shows a 1D framework structure containing bimetallic 42-membered quadrangular ring units. The adjacent 1D chains are interacted forming a 3D supramolecular network structure through multiform hydrogen bond interactions. In comparison with 1, polymer 2 is a new rampart-type chain and each chain is interacted with each other through hydrogen bond interactions to lead a 2D layer. The luminescent properties of the polymers 1 and 2 were investigated in the solid state at room temperature.
